Luke indicated that Jesus continued to talk about sparrows and humans. Jesus said that even the hairs of their heads (ἀλλὰ καὶ αἱ τρίχες τῆς κεφαλῆς ὑμῶν) were all counted (πᾶσαι ἠρίθμηνται). They were not to be afraid (μὴ φοβεῖσθε), since they were of more value than many sparrows (πολλῶν στρουθίων διαφέρετε). This verse is similar to Matthew, chapter 10:30-31, indicating a Q source. Jesus, via Matthew, said that God, the Father, could number all the hairs on their head (μῶν δὲ καὶ αἱ τρίχες τῆς κεφαλῆς πᾶσαι ἠριθμημέναι εἰσίν). They should not be afraid (μὴ οὖν φοβεῖσθε), because they are more valuable than many sparrows (πολλῶν στρουθίων διαφέρετε ὑμεῖς). If God the Father cared for these insignificant birds, how much more was he concerned about humans. There was a continual theme about not being afraid. Do you think that you are more valuable than a few stray birds?
